tion of the container, and having one side formed of a relatively thin transparent sheet material, such as glassine, regenerated cellulose sheeting or similar transparent sheet material, and the like.

One of the' serious handicaps in using ay sheet of this typeA in 'a container is. that it is quite responsiveto temperature changes, this characteristic frequently causing the stripping or breaking of the sheet away from the container. For this reason the so-called "window container, having a relatively small transparent sheet incorporated therein, has been found to be unsatisfactory.

An object of this invention is to provide a simple and inexpensive method of incorporating a. sheet of relatively thin transparent material in acontainer, in such a manner that the container may be formed on standard container manufacturing machines, shipped in a flattened condition, Y

and lled either by hand or machine.

Another object is to provide means for incorporating a sheet of transparent material in a container for display purposes, said sheet being secured to the container in such a manner that it will not strip away from the container in response to temperature changes.

Another object is to provide a strong, durable and moistureproof container, which is especially adapted for packaging and displaying nuts, fruits, foodstuffs and the like.

Other objects and advantages of this invention will be apparent during the course of the following description.

The preferred method of forming containers is shown in Figures 1 through 12. Fig. 1 illus- 3Q Atrates the blank from which the body of the container isformed, the blank indicated by the numeral 4 8 being formed of cardboard, which is of suiiicient thicknessto form a strong and durable container, and is easily folded. It is contem- 35, ,plated that the blank 48- may be moistureproofed by vany suitable method; such. as by laminating it with .moistureproof sheeting, or otherwise. The blank 48 is provided with longitudinal slits 4| at the top, andsimilar4 slits 42 atthe bottom, 40 while the blank is scored longitudinally at 43 with scorings connecting .the ends of the slits 4I and 42. ATransversescorings 44 are provided at `the top o f thel blank 48, and similar scorings 45 aife provided at the bottom of the blank. 45 One side of thev blank 48 ,is then folded over on itself along the scoring 43, and the slits 4I and 42, forming a. side 46, and a `rectangular transparent sheet 58, which is the same length as the blank 48 -and is slightly wider than the back 41, 50 vis placed over the blank, and is adhesively secured to the blank 48 along the longitudinal edges of the side 46, and along the opposite edge of the blank 48, as clearly shown in Figs. 2 and 3. Itis. contempla ed that th container may be attened form bythe container manufacturer.

.The opposite side ofxthe blank 48jis then folded at right angles-to the blank 40, along the scorings \-43 Aand thevslitsv 4| and 42, forming the side 48, 60, and at the same time the side 46 is similarly fold- 'ed outwardly providing the form shown in Figs. @and 5. 'I'he bottom end of the container is then formed, as shown in Figs. 6,7 and 8, by folding inwardly the lower ends ,of the sides 46 and 48 05 along the scorings 45, flaps 46a and 48a, andthe lower end of the sheet 58 is folded over the end flaps 46aand "informing a triangularly shaped fold 49.4 The lower end of the blank 48, constituting an end flap 5I'a, isiprovided with a suit- 70 able adhesive 52 and is folded along the scorings i 45, over the end flaps 46a and 48a and .the vfold 48. The adhesive 52 `holds the'end aps and the fold .49 securely in place. The container is then in condition to be filled having the bottom end closed and the'top. end open. I'he filling operation may be accomplished either by hand or machine.

By having the sheet 58 secured tothe outer surfaces of the sides 46 and 48 and extending over the edges thereof, the stripping of the sheet 5 from the cardboard is prevented and the ilexibility of the cardboard permits thetransparent sheet to expand and contract in response totemperature changes. i v

'I'he top of the container is then similarly fold- 10 ed and secured, forming top end flaps 46h, 46h and 5Ib and producingj the finished container shown in Figs. 9 through 12.

Fig. 13 discloses a slight "modification in the manner of folding the ends. In this form the end l5 flaps are formed and folded in a manner similar to that disclosed in Figs. l through l2, with the exception that the'fold 49 is folded .over the outside of the end'flap 5Ib instead of being folded under, and an adhesive 52 is placed on its vouter 20 surface. y A first modified method of forming my container is shown in Figs. 14 through 19. The blank 68 is similar to the blank 48 of the preferred form. Only the top end of the blank 68 is shown, as 25 it is obvious from a study of the preceding figures, that the blank 68 can be similarly formed at the bottom end. Longitudinal slits 6I and 62 are in registry with longitudinal scorings 63, while a transverse scoring 64, at the intersection 30. of the slits 6I and the scorings 63. is also provided. i

It is obvious that the transverse ends of the y, transparent sheet may terminate at an'y point between the transverse scorings and the ends of 35" the blank. Y n As in 'the preferred method, one side 66 is formed by folding one side of the blank 68 overv on itself, and a transparent sheet, 61 is placed over the blank 68 and is adhesively secured to 40 the blank 68, along the longitudinal edges of the side 66 and the opposite edge of the blank. The sheet 61 in this form of the invention', is of the same width as that in the preceding form, butis shorter in length, as it does not extend to the end 45 of the blank 68, but terminates the distance be- I low the end of the blank indicated at.X This results in the saving of a .substantial amount oi'- transparent sheeting while producing a container having the advantages. of the preceding form. 50

After the sheet 61 is thus secured to the blank 60, the opposite side is then folded at right angles to the blank along the scorings 63 and slit 6| forming the side 68, and at the same time the side 66 is similarly folded outwardly, providing the 5 5` form shown in Fig. 16. The bottom of the container is then formed by folding inwardly the lower ends of the sides 66 and 68 along trans. verse scorings, forming flaps 66a and 68a, and the lower end of the sheet 61 is folded over the iiaps 50.,

66aand 66a, forming a. fold 69. 'Ihe lower end of the'blank 68, constituting an vend flap 1I, is provided with a suitable adhesive 12, and is folded along the scoring over the end flaps 66a and 68a and the fold 69. The container is now 55 ready to be filled, as hereinbefore indicated. After the llingpperation is completed, the top end may be similarly folded and secured.

A still further modified method of forming myl container is shown in Figs. 20 through' 27. 1h70, this method, the blank 18 at the corners is cut out as indicated at `70a.y 'I 'he blank 18 is provided with longitudinal slits 13 at the bottom and similar slits at the top, while the blank is scored longitudinally at 74 and transversely at 1l.

2,018,621 Y As in the preceding forms of the invention disclo'sed, one side of the blank 10 is folded over on itself along the scoring 13, forming a side 16, and a sheet of transparent material 80, which is the same length as the cut-off sides of the blank 10, is placed over the blank 10 and is adhesively secured to the longitudinal edge of the side 16, and along the opposite longitudinal edge of the blank 10, as shown in Fig. 2l.

- The opposite side of the blank 10 is then folded at right angles to the blank along the longitudinal scoring 14 and the slits 13 forming the side 18, and at the same time, the side 16 is similarly folded outwardly providing the form shown in Figs. 23 and 24. 'I'he bottom of the container is then formed by folding inwardly the lower ends of the sides 16 and 18 along the scoring 15, forming the bottom end flaps 16a and 18a, and the lower` end of the sheet is folded over the end flaps 16a and 18a forming a fold 19. The

lower end of the blank constituting an end flap 11a isfolded along the scoring 15 over the end 1 flaps 16a and 18a and the fold 19. Adhesive -is placed on the part of the end flap 1 fa which is in contact with the end flaps when it is folded over.

vThe container is then in the form shown in Figs.

25, 26 and 27 in which the top is open for filling. 'I\'he top of the container maybe similarly folded and secured.

A third vmodified method of forming'my container is shown in Figs. 28 through 38.l In this method tabs are employed in place of adhesive to secure the end flaps to the container.

The blank 90 is cut to form tabs 90a, the blank being provided with longitudinal scoring 93. transverse scoring at the bottom 95 and transverse scoring at the top 94. 'Transverse slits VH13 are adapted to receive the tabs 96a when the container is folded. One side of the blank 90 is then folded over onitself along the scoring 93 forming a'side 96, and a transparent sheet |00, whichis the same length as the blank 90 and slightly wider than the back-91, is placed over the blank and is adhesively secured thereto, along the edge of the side 96 and the opposite edge as shown'in Fig. 29.

The opposite side of the blank 9!) is then folded at right angles to the blank along the scoring 93,' forming the side 98, and at the same time the side 96 is similarly folded outwardlyproviding the form shown in Figs. 31 and 32. The bottom of the container is then formed by folding inwardly the lower ends of the sides 96 and 98 along the scoring 95, forming flaps 96a andl 98a, and the lower end of the sheet |00 is folded over the aps 96a and 98a forming a triangularly shaped fold 99, and the lower end of the blank 90, constituting an end ap lilla, is folded along the scoring 95A over the end flaps 96a and 96a and the foldl` 99. The tabs a extending from the sides of the flap lola are inserted in the transverse slits |93 in the sides 96 and 96.

The container is now in condition to be filled with the bottom closed and the top open, as shown in Figs. 33, 34 and '35. After the container is filled, the top of the container is formed and secured in asimilar manner, producing the con g tion or sacricing the advantages thereof, and that the various embodiments of the invention herein disclosed are illustrative only, and 'that my invention is` not limited thereto.
